After years of enduring and enjoying the heat & humidity of the Oklahoma tropics, my son and daughter-in-law forced an armored mesh riding suit on me. It feels like a towel. If I hit the pavement, I think I'd die. The thing was even hotter than my leathers, and I thought I was going to pass out - Then they showed me how to remove the rain liner.
I don't feel as secure as I do in my leathers, but I'm trying to get used to it. When the heat gets to be too much, you have to do something, and these days, the heat has started to affect me. I may look stupid, but I think I look stupid riding around in racing leathers, too. I had to get used to that a few years back, until I can't imagine being without them. I supose 'going mesh' is better than going without, and it beats falling off from heat prostration.
